The motivation of this project is to solve a problem that we currently face working on a project called 27bards, which seeks to revolutionize the tour industry by constructing a database of currently existing tour operators with the Airbnb-like twist of allowing the average person to make money as a part-time tour guide. We wanted to apply machine-learning techniques to make sense of the largel...

A knight‟s tour on a board is a sequence of knight moves that visits each square exactly once. A knight‟s tour on a square board is called magic knight‟s tour if the sum of the numbers in each row and column is the same (magic constant). Knight‟s tour in higher dimensions (n > 3) is a new topic in the age-old world of knight‟s tours. In this paper, it has been proved that there can‟t be magic k...

We consider the following natural heuristic for the Symmetric Traveling Salesman Problem: solve the subtour relaxation, yielding a solution x∗, and then find the best tour x̄ that is compatible with x∗, where compatible means that every subtour elimination constraint that is satisfied at equality at x∗ is also satisfied at equality at x̄ . We prove that finding the best compatible tour is NP-hard...

Tour guide plays an important role for achieving the overall service quality of a tourism supply chain. The service quality of tour guide can be improved by promoting service effort & service ability that are asymmetric information to travel agency. Two types of incentive contracts are commonly used by travel agency to motivate tour guide improving the service quality. These are a pooling contr...

We use the halo occupation model to calibrate galaxy group finders in magnitudelimited redshift surveys. Since, according to the current scenario of structure formation, galaxy groups are associated with cold dark matter halos, we make use of the properties of the halo population in the design of our group finder. The method starts with an assumed mass-to-light ratio to assign a tentative mass ...

Study and work operations are being transformed with the uses of technologies and are consequently becoming global. This paper outlines lessons learned based on the international study tour that Australian Bachelor of Information Systems students undertook. This research identifies that for the study tour to be successful, students need to gain skills that global citizens require. For example, ...

Orthologs are widely used for phylogenetic analysis of species; however, identifying genuine orthologs among distantly related species is challenging, because genes obtained through horizontal gene transfer (HGT) and out-paralogs derived from gene duplication before speciation are often present among the predicted orthologs. We developed a program, "Ortholog-Finder," to obtain ortholog data set...
